Satellite Use: Nimiq 4 has two payloads for Canadian broadcast services. The main payload will provide specialty television and foreign language programming. The second payload has six beams covering Canada for such advanced services as high-definition television. Nimiq satellites are dedicated to the provision of direct-to-home services for Bell TV.

Mission Profile: The Proton M launch vehicle, utilizing a 5-burn Breeze M mission design, will lift off from Pad 39 at Baikonur Cosmodrome, Kazakhstan, with the Nimiq 4 satellite on board. The first three stages of the Proton will use a standard ascent trajectory to place the Breeze M fourth stage and the Nimiq 4 satellite into a suborbital trajectory from which the Breeze M will then place itself and the spacecraft into a low Earth circular parking orbit. Once Nimiq 4 is in the parking orbit, it will be injected into a geosynchronous transfer orbit following four additional burns of the Breeze M.

More Information: Live webcast at www.ilslaunch.com will begin approximately 20 minutes before liftoff. Satellite coordinates for the live broadcast will be available on the ILS web site a few days before launch. General mission information and launch status updates are available at the website or on the ILS U.S. domestic Launch Hotline at 1-800-852-4980.

Why? So called "Briz-KM problem" in GOCE case were glitches in ukrainian PCB in the guidance block. Should be cured with replacement on the copy. It can raise quality control issue in Kharkov, but can't delay other missions for Breez.

The assembly of ascent unit with Proton-M rocket is finished. The rocket is transported for the fuelling of low pressure tanks of Briz-M upper stage by propellants. The rollout of rocket to the launch pad 200/39 is planned on September 15th.

"The launch of Proton M launch vehicle with Canada’s Nimiq 4 communications spacecraft on board has been delayed. A component malfunction was detected in the LV control system during on–pad tests. The faulty component will be duly replaced by a spare.

The launch has been moved to the scheduled contingency day, September 20, and is planned at 01:48 Moscow summer time [at 21:48:00 UTC on September 19 - anik]"
